Black Jack visits a neighborhood, where he hopes to get payment for a previous job. However, he instead meets Hotch, a man who constantly complains about the shaking caused by the bullet trains that speed by and literally shake up his neighborhood. Black Jack performs surgery on Hotch's wife, but pauses in the middle to wait for the shaking fit to pass. When he tries to resume again, the train shakes again, until finally Hotch's demands to stop the trains are met and his wife can be saved.
